The communication function of the sensing network platform needs to be realized by the communication server. The management function of the management platform needs to be realized by a device such as a management server. In order for the user platform to realize functions such as human-computer interaction, it needs to be realized by APP or software having application functions. These infrastructures for realizing the smart functions of smart cities are collectively called physical entities. The realization of different platform functions in smart city functional systems requires support from different types of physical entities. Build the physical architecture of the smart city with the functional system of the smart city. That is, it is an object layer, a sensing network layer, a management layer, a service layer, and a user layer.

Among them, the physical entity of the object layer is a smart object having a detection / control function collectively called a detection control system because it is used to realize the detection / control function of the object platform. Physical entities in the object layer cover all areas of smart cities that realize smart functions, and each area in smart cities has its own physical entity that realizes detection and control functions. In the smart city functional system, it is the sensing network platform that is connected to the object platform. Similarly, in a physical system, it is the sensing network layer that is connected to the object layer. The sensing network layer includes various communication devices for transmitting information, and realizes the communication function of the sensing network platform through these devices. The sensing network layer is the first barrier to information transmission in the object layer, and the communication device of the sensing network layer can receive, store, and transfer a large flow rate of information. On the other hand, the communication device has a communication protocol conversion function because it is necessary to transmit the received information to another layer. The superstructure of the sensing network platform in the smart city functional system is the management platform. The management layer has various facilities for realizing the business management function of the management platform, and these facilities mainly refer to various management servers composed of various hardware and software systems. The management server is mainly operated and managed by operators in each functional field of the smart city. The management server in the management layer is the necessary support for realizing the functions of the smart city functional system. The service layer of the physical system corresponds to the service platform of the functional system and is higher than the management layer. The corresponding service layer requires physical entities to implement these two functions. That is, the physical entity of the service layer includes a social / public network server, a government server, and an operator service platform server. The user platform is a platform for realizing human-computer interaction in smart cities, and its functions are realized by the user layer in the physical system.

Users of smart cities include individuals, city builders and city managers who live in smart cities, so different users use different physical entities.

The smart city function system has a five-platform structure, and each platform supports one function. The five platforms are connected to each other and jointly realize the smart functions of smart cities. The physical system of the smart city is a support for the functional system of the smart city, and the function of the smart city cannot be realized without the physical system. The smart city's five-platform functional system divides the smart city's physical system into five physical layers. There is a one-to-one correspondence between the physical layer and the functional system platform, and each physical layer supports the realization of functions on the corresponding functional system platform. The platforms of each functional system are interconnected and interdependent, so each physical layer cannot be independent of each other. There is an interaction relationship between the physical layers, and the interaction between the physical layers is mainly realized by the flow of information between the physical layers. Each physical layer has an interface for the flow of information, and information flows between each physical layer, creating conditions for interconnection and interaction between physical layers. In smart cities, the flow of information at each physical layer connects a wide range of physical entities in each functional area of smart cities, and further enables detailed analysis and precise control of smart cities. It can be said that the operation of information in a smart city "brings" the physical entity to life, and that the physical entity has the corresponding value and meaning because the information is operated. Therefore, constructing an information system via a smart city physical system is an indispensable part in constructing a smart city system.

The physical system of a smart city has a five-layer structure consisting of an object layer, a sensing network layer, a management layer, a service layer, and a user layer from the bottom to the top. According to this, the information system of the smart city has a five-domain structure of an object domain, a sensing domain, a management domain, a service domain, and a user domain from the bottom to the top. The five-domain structure of the smart city information system has a one-to-one correspondence with the five-layer structure of the physical system. That is, the object domain corresponds to the object layer, the sensing domain corresponds to the sensing network layer, the management domain corresponds to the management layer, the service domain corresponds to the service layer, and the user domain corresponds to the user layer. Since smart cities need to realize both comprehensive detection and accurate control, two types of information, detection information and control information, are required. The detection information is various information detected by the detection system of the object layer. For example, home appliances equipped with household detectors, detection information such as brightness, current, room temperature, and humidity. Smart gas meters and water meters that detect information such as flow rate, pressure, magnetic environment, and earthquakes in the energy field. Information such as the position detected by the vehicle equipped with GPRS ... The control information is the control information transmitted by the user layer to execute the corresponding control. For example, in the residential field, control information such as home appliance switch control, air conditioning control, refrigerator temperature control, and curtain opening / closing control. In the energy field, control information such as on / off valve control of natural gas meters and water meters, and alarm control by natural gas meters and water meters. The object domain and the user domain are the two extremes of the smart city information system, of which the object domain is the start point of detection information transmission and the end point of control information reception, and the user domain is the end point of detection information reception and the start point of control information transmission. Is. As a result, in the smart city information system, the operation of detection information starts from the object domain, goes through the sensing domain, management domain, and service domain, and finally reaches the user domain, and the operation of control information starts from the user domain. It can be seen that it starts, goes through the service domain, the management domain, and the sensing domain in order, and finally reaches the object domain. Therefore, in an information system, the operation of information forms a closed loop, in which detection information flows from bottom to top and control information flows from top to bottom.

The ultimate goal of building a smart city is to fully utilize the functions of the smart city and provide services to humans. Therefore, the functional system is the core of the smart city system, and the construction of the smart city system needs to start from the construction of the functional system as a starting point and a foothold. Realization of smart city functions requires relying on the support of physical entities, and without physical entities, building a smart city functional system is an unrealistic story, so physical systems are the construction of smart city functional systems. It becomes the basis. In a physical system, a physical entity needs to have a function of flowing information between physical entities in order to realize its operation. Without the flow of information between physical entities, no matter how rich and perfect the physical system is, the functionality of a smart city cannot be achieved. Therefore, the information system is also an indispensable part for the construction of the smart city system. In summary, smart city systems include functional systems, physical systems, and information systems. Functional systems, physical systems, and information systems are all indispensable for smart city systems. The functional system is the core of the smart city system because it points the direction of the smart city's top-down design. On the other hand, the physical entity in the physical system supports the realization of the smart city function, and the operation of information in the information system provides a method for the realization of the smart city function. Therefore, the physical system and the information system closely surround the functional system and are on both sides of the functional system. The functional system of the smart city has a five-platform structure of an object platform, a sensing network platform, a management platform, a service platform, and a user platform. The physical system of a smart city has a five-layer structure of an object layer, a sensing network layer, a management layer, a service layer, and a user layer. The smart city information system has a five-domain structure of an object domain, a sensing domain, a management domain, a service domain, and a user domain. Since each of the five platforms in the functional system has its own platform function, the realization of each platform function requires support by the corresponding physical entity and the operation of information in the corresponding information domain. Therefore, in the smart city architecture diagram, the object platform of the functional system corresponds to the object layer of the physical system and the object domain of the information system, and the sensing network platform of the functional system corresponds to the sensing network layer of the physical system and the sensing domain of the information system. The functional system management platform corresponds to the physical system management layer and the information system management domain, the functional system service platform corresponds to the physical system service layer and the information system service domain, and the functional system user platform. Corresponds to the user layer of the physical system and the user domain of the information system.

As shown in FIG. 2, the smart city functional system is realized by an organic combination of a plurality of IoT functional systems. Since a smart city is a large-scale and complex system, it is impossible to realize all the functions of a smart city with only one IoT system. Therefore, a single IoT functional system is the basis for forming a smart city functional system. Among them, when the IoT functional system constitutes the smart city functional system, some IoT functional systems are in a parallel relationship. For example, IoT1 and IOTa in FIG. Some IoT functional systems themselves are in the relationship of organic combinations. For example, IoT2 and IoT3. This also reflects the complexity of the smart city's functional system. However, as a whole, smart city functional systems are rational and scientific when divided into five platforms: object platform, sensing network platform, management platform, service platform, and user platform.

The platform of the smart city function system and related sub-platforms will be further described below.
1. Object Platform The smart city object platform is the interface between everything in a smart city and the IoT system. The function of the object platform is to realize detection and control, the detection unit of the detection device detects the detection information and realizes the detection function, and by operating the IoT system, the user through the sensing network platform, management platform and service platform. The detection information is converted into control information by the user, and then transmitted to the control device of the object platform through the service platform, management platform, and sensing network platform, and the control is executed by the control unit of the control device, and the closed loop information. The structure is formed. Anything that has a detection function and a control function can be an object. The object can be a person, an object, or a combination of a person and an object. Further, the object may be an individual, a set of a plurality of individuals, an individual of a specific type, or an IoT composed of a plurality of individuals.

Generally, the detection function of the object platform is realized by the detection unit of the detection device, and the control function is realized by the control unit of the control device. The detection device and the control device can automatically execute self-control, and can also execute control based on the received control information. When the object is a smart object, the detection function and the control function are realized by the detection unit and the control unit in the object. When the object is human, the detection and control functions are realized by human detection organs and control nerves. When an object is a combination of people and things, or a group of people, detection and control functions are realized through communication between people.

The technical means for achieving this are as follows.
The main function of the object platform is to realize the detection and control functions, and the detection and control functions are realized by the respective detection devices and control devices. When the detection unit of the detection device detects the detection information and transmits it to the sensing network platform by the communication module and the sensing network platform transmits the control information, the communication module of the control device receives the control information and the control unit of the control device receives the control information. Take control.

1) Detection function Since the perceptual function of the object platform is a prerequisite for the existence of IoT, IoT disappears without detection information, and it is impossible to operate it. The detection function of IoT is to realize the detection function by various detection technologies, and the detection device and the detection technology differ depending on the type of detection information. Depending on the type of detection information, the detection function includes detection of IP audio / video information and detection of non-IP audio / video information. Among them, the detection of IP audio / video information mainly refers to the information detected by the camera, and most of the detected information is non-IP audio / video information. For example, label reading / writing, position acquisition, radio frequency identification, QR code scanning, etc., and pressure sensor, temperature sensor, humidity sensor, pressure sensor, flow rate sensor, liquid level sensor, force sensor, acceleration sensor, torque sensor, etc. Includes sensors that measure physical quantities.

Since the object platform is an entry point for the IoT system to acquire external information, and the detection function of the object platform is an important means for the object platform to acquire the detection information, the level of detection technology is the object. It determines the comprehensiveness of the information detected by the platform and also determines the richness of the content of the IoT system. The control function of the object platform is the execution of the control information obtained after the detection information has passed through the entire IoT system.

2) Control function Generally, the control function of the object platform is realized by the control device. The control device can automatically execute self-control, and can also execute control based on the received control information. When the object is a smart object, the control function is realized by the control unit in it. Smart control is a function that automatically executes some kind of control or self-control without receiving external interference. When the object is human, the control function is realized by the human control nerve. When an object is a combination of people and things, or a group of people, control functions are realized through communication between people.

In smart cities, smart control technologies are ubiquitous. For example, smart home central control system for intelligent centralized control of environmental lighting system, home theater audio / video system, security surveillance system, public / background music system, air conditioning system, electric curtain and other series of home control systems. include.

2. Sensing network platform As the name implies, the function of the sensing network platform is communication, and the smart city sensing network platform mainly realizes mutual communication between the object platform and the management platform. Communication refers to the efficient delivery of messages from one location to another. In smart cities, it is mainly a method of telecommunications such as telephone and network. Among various communication methods, a communication method that uses an "electric signal" to convey a message is called telecommunications. This communication can transmit useful information efficiently and without distortion while suppressing unnecessary and harmful information during transmission, and also has storage, processing, collection and display functions, which is fast, accurate and reliable, and It is rapidly developing and widely used because it has the advantage of being unlimited by time, place, space, and distance.

Communication in smart cities is mainly based on telecommunications, which uses telecommunications to convey information and transmits telecommunications over communication networks to carry out information transmission. A communication network is a system that uses a switchboard and a transmission device to interconnect geographically distant user terminal devices with various communication means by a specific connection method to perform communication and information exchange. The smart city's sensing network platform corresponds to the sensing domain of the information system and contains four physical entities. That is, the communication module of the detection device, the communication module of the control device, the IoT intelligent gateway, the public network, and the operator communication server. The IoT intelligent gateway is an IoT intelligent gateway having a smart management function, unlike a conventional gateway. Public networks mainly refer to mobile public networks, the Internet, and the like. The sensing network platform enables interactive detection and control information between the object platform and the management platform in the smart city IoT system.

The sensing network platform for smart city IoT systems is a combination of sensing network platforms for IoT systems in all industries. The sensing network platform and the object platform are connected via the detection device and the control device, and are connected to the management platform via the communication server of the management platform. The communication module of the detection device transmits the detection information to the IoT intelligent gateway, and the IoT intelligent gateway transmits the detection information to the operator communication server via the public network. The operator management platform appropriately processes the detection information and then sends it to the user via the service platform. The user sends the control information, the control information is sent to the operator communication server via the service platform, and the management platform properly processes the control information and then sends it to the IoT intelligent gateway via the public network by the operator communication server. .. The IoT intelligent gateway aggregates information, sends it to the communication module of the controller, and controls the object by the controller.

There are various types of detection information uploaded by the object platform. For example, audio information, video information, geographic information, data information, control information, and other information. Different information has different transmission interfaces, and various kinds of information are transmitted to the IoT intelligent gateway through the respective interfaces. The gateway stores detection data via acquisition adapters and data transmission functions, and performs protocol conversion, routing, application registration, etc., and manages device settings, identification, status management, application management, performance management, security, etc. The function can be realized. After properly processing the information, the gateway transmits the information via the Internet, mobile communication network, satellite communication network, PSTN, IP network and other networks.

3. Management platform The smart city management platform processes, stores, classifies, identifies, and analyzes information in smart city systems, realizes management functions, provides support to service systems, and is an integrated management system for the entire smart city system. be. The smart city management platform corresponds to the management domain in the information structure, is equipped with a detection information management system and a control information management system, and corresponds to the operator management server and various facilities connected to the server in the physical structure, and the information structure. It is a carrier of detection information management system and control information management system in Japan. The operator management server may be any of a plurality of operator servers that provide the same service, a plurality of operator servers that provide different services, or a specific operator server that provides a specific service.

The smart city management platform is not only a management software platform, but also a management system that combines tangible and intangible ones used to operate smart cities. The most important role of this platform is to maximize the use of urban resources. Its core mission is to comprehensively manage the smart city IoT system, including basic management and application management. Basic management is the operation management of the IoT management system and management of background data related to the system, and application management is the detection information of the object platform transmitted from the sensing network platform and the control information transmitted from the user platform by the operator integrated management system. Is to accept comprehensively. Management by the management platform is mainly reflected in the integration, classification, and processing of various types of information. The designed software program comprehensively processes detection information and control information, and converts detection information and control information. conduct.

The smart city management platform is realized by the following technical means.
The IoT management platform realizes various professional system management functions by performing data collection, protocol conversion, data storage / processing, data sharing, and business process arrangement for various detection / control information, public service information, and network communication. It provides services for the production and management of the company and realizes the function as a management platform. The functions of the management platform include basic management functions and advanced management functions. Among them, the basic management functions are information resource exchange, market resource exchange, regulation, maintenance, public data integration, public data storage, public data processing, public data access, identification management service, geographic information service, service management. , Including user service management and so on. Application management is the management of information about users. For example, a management function for the collection, identification, analysis, processing, etc. of detection information uploaded by the sensing network platform, and a management function for the identification, analysis, processing, etc. of control information transmitted by the user via the service platform.

In the smart gas subsystem of the smart energy system, the gas company management platform is the management platform of the smart gas subsystem, and the gas company management platform performs integrated management of the entire smart gas subsystem, including basic management and business management. Basic management refers to the operational data management of the smart gas subsystem and some related background processing. Business management is integrated management of the gas business, including account opening. For example, when the prepaid balance in the gas meter is insufficient, the information that the gas meter automatically uploads that the prepaid balance is insufficient, that is, the detection information is transmitted to the management platform via the sensing network platform. After identifying and analyzing this detection information, the management platform sends information on insufficient balance to the user platform via the service platform. Upon receiving the information that the balance is insufficient, the user determines that it is necessary to pay the gas fee, and sends the payment instruction and the payment amount to the management platform via the service platform. The management platform sends the payment instruction to the gas meter according to the payment instruction and the payment amount by the user, accumulates the purchased gas amount in the gas meter, and makes the remote payment. In this process, the gas company management platform analyzes and processes the information that the gas meter is out of prepaid balance, converts it into an information format that the user can understand, and sends it to the user, as well as the information on the payment by the user. It is analyzed and processed by the gas company management platform, converted into an information format that can be recognized by the gas meter control module, and the gas meter is controlled.

4. Service platform The smart city service platform is a platform that provides services to users and realizes service functions, and the service content includes public services and operator services. Public services are government-led, public information and data processing services provided to smart city systems, such as information resources, market resources, legal compliance, and public data. The operator service is an operator business service provided by the operator.

The smart city service platform corresponds to the service domain in the information structure, includes the public detection service system, the government detection service system, the operator detection service system and the operator control service system, and also corresponds to three parts in the physical structure, that is, , Social and public network server, government server, operator service platform server. The operator service platform server may be either a plurality of operator service platform servers providing the same service, a plurality of operator service platform servers providing different services, or a specific operator service platform server providing a specific service.

The technical means for achieving this are as follows.
The service platform accesses, exchanges, and routes various basic services and resources via the service bus, provides public services to users, and realizes integrated interconnection of messages, data, events, and services.

The service platform is managed by service registration, various basic services can be registered or unregistered with the service platform, and are transmitted for message, data, event, service exchange between the platform and the user through service transmission management. Provide the above guarantee. It transforms various types of data through protocol conversion services, and stores and processes them to provide big data services to users.

Service quality management and service security management ensure service quality by performing service security certification, certification, service QOS monitoring, etc.

Smart city service platforms are actually big data. With the development of e-commerce, IoT, social networks, etc., new data sources and data collection technologies are emerging, the types of data are increasing in each industry, and the complexity of big data is increasing with various unstructured data.

Fifth, User Platform The function of the IoT user platform is to enable users to enjoy the services provided by the IoT system. Users output their needs through human-computer interaction using various user terminals and enjoy the services provided by the entire IoT system.

The function of the smart city user platform is to realize a service in which the user enjoys the service provided by the smart city system. The user platform corresponds to the user domain in the information structure and the user terminal in the physical structure. Users can output their needs and enjoy the services provided by the entire smart city system through human-computer interaction using various user terminals.

The users of the user platform can be a single individual user or a group of users, a person or thing, a corporate user or a government user. As long as it is the target of the service provided by the smart city system, it is the user. Generally, in the information structure, the user refers to all the entities that accept the services provided by the smart city system, which is an abstract concept. In the physical structure, a user refers to a specific user and may be either a plurality of users who enjoy the same service, a plurality of users who enjoy different services, the same user who enjoys different services, or a specific user who enjoys a specific service.

The technical means for achieving this are as follows.
The service platform provides users with public services via networks (Internet, 2G / 3G / 4G, satellite networks, other networks). Service information types include audio, video, public services, payments, GIS maps, business data, device status, network topology, and more. Users receive service information via web pages, dedicated customer interfaces, apps, computers, and so on.

For smart cities, the population of users is very complex and diverse, and the needs of users are also involved in various areas of the industry. The feature richness of the user platform directly determines the smart level at which the user enjoys the service, and determines the degree of human liberation. Functions such as network personal account inquiry, remote control of household energy, and remote control of smart home systems can be realized via the user platform.

1) Inquiry of personal account via network In order to protect the information security and privacy of users, most remote control by users requires the registration of their own account, which cannot be operated without logging in to the corresponding system. .. For example, a gas user using smart energy can log in to the smart energy system and perform personal account information inquiry, balance inquiry, past consumption record inquiry, gas price information inquiry, and the like. In smart cities, those who need to go out can log in to their account with the taxi app, check the relevant information on available cars, cars and drivers nearby, and choose a taxi according to their needs. Can be called. In the smart medical system, if the patient is a user, he / she can log in to the smart medical system and check the personal information, specialties, success stories, number of appointments, attendance status, etc. of doctors in each department. If the doctor is a user, he / she logs in to the smart medical system, checks the patient's medical record, treatment progress, appointment information, online treatment data (blood pressure, blood sugar, blood lipid, pulse, etc.) and quickly grasps the patient information. And you can make a diagnostic plan quickly.

2) Remote control of household energy Household energy includes household water, household electricity, household gas, and household heating. Since water, electricity, gas, and heat are the most indispensable parts of the daily life of the inhabitants, smart household energy really benefits people. Home smart energy systems allow people to check and remotely control the use of water, electricity, gas and heat in their homes through a user platform. Taking a home smart gas system as an example, a user can log in to the smart gas system, query gas usage and account balance via the user platform, and make remote payments via the user platform payment system. can. The gas company management platform receives information on payment by the user, sends control commands to the gas meter, accumulates the amount of purchased gas, and completes the payment. As another example, a user has been away from home for a long time on a business trip. Since the gas has not been used for a long period of time, the smart gas meter automatically closes the valve for indoor safety, and the user obtains the valve off information detected by the gas meter via the user platform. If you want to open the valve to continue using the gas, you can apply for valve on through the user system of the user platform. The gas company confirms the safety on the gas meter side and opens the valve according to the user's request.

3) Remote control of smart home systems Smart homes are a part of smart cities and are closely related to people's daily lives. Smart homes generally use different smart control technologies for different household items to provide smarter, more comfortable and more convenient services. Smart home smart controls almost always do not require a user to go through, and smart homes perform smart controls directly based on detection information, adjust their own parameters, and provide people with the best service mode. These smart controls are for the benefit of the user and enhance the comfort and convenience of the user. These controls in the smart home are either authorized and agreed by the user or pre-approved by the user. In essence, the smart control process of a smart home is actually the process of operating a complete IoT system with a complete five-domain structure. Therefore, the essence of a smart home is IoT, a special subsystem of a smart city called a smart home subsystem.

The smart city functional system includes five functional platforms: an object platform, a sensing network platform, a management platform, a service platform, and a user platform. Since the smart service functions of smart cities are realized by a huge composite IoT system composed of countless IoT in the city, the functional platform in the smart city functional system is the functional platform in these countless IoT. It is also a multi-functional platform composed of, and is divided into multiple level sub-platforms according to the industry, field, and product related to human activities. For example, by industry and sector, the five functional platforms of Smart City are first-level smart transportation sub-platform, smart medical sub-platform, smart energy sub-platform, smart government sub-platform, smart environmental protection sub-platform, and smart. It is divided into home sub-platform, smart education sub-platform, smart community sub-platform, smart city management sub-platform, smart tourism sub-platform, smart logistics sub-platform, etc. Sub-platforms cover various industries and areas of urban life. In the same industry or sector, sub-platforms can be further subdivided to form second-level smart city sub-platforms, depending on the product or characteristics. For example, in the field of smart energy, depending on the energy, the smart energy sub-platform is further divided into a smart electric power energy sub-platform, a smart gas sub-platform, a smart water business sub-platform, and a smart thermal energy sub-platform. Similarly, the second level smart city subplatform can be further subdivided to form a lower level smart city subplatform. For example, smart gas sub-platforms are divided into smart public gas sub-platforms and smart household gas sub-platforms.

In short, in urban activities, people can build complex IoT systems in various industries and fields according to their needs and realize various smart service functions. All smart service features in these industries and disciplines will be integrated into the five functional platforms of the smart city composite IoT system. Therefore, the smart city's functional platform is open, allowing people to add more smart service features as needed and ultimately form a smart city with functional diversity.

1. Object Sub-Platform As shown in Fig. 3, the smart city object platform is a platform for realizing detection and control functions in the smart city composite IoT system, and all detection and control functions are reflected in the object platform. There is. The smart city object platform is composed of various levels of object sub-platforms, which belong to various industries and various fields, and have an inclusive and parallel relationship with each other, and comprehensive detection of smart cities. Jointly realize control functions.

Depending on the industry and sector, smart city object platforms are first divided into first-level smart transportation object sub-platforms, smart medical object sub-platforms, smart energy object sub-platforms, smart government object sub-platforms, smart environmental protection object sub-platforms, etc. .. Object sub-platforms in various industries and fields are platforms that realize detection and control functions in IoT systems in the industries and fields. These object sub-platforms enable different types of detection and control capabilities to meet people's needs for smart services in different industries and disciplines. For example, in the transportation sector, people face a series of problems such as traffic congestion, lagging behind traffic management methods, frequent traffic accidents, and parking difficulties. The purpose of creating smart traffic is to realize smart traffic management and services by constructing a smart traffic IoT system, and to solve the above-mentioned traffic problems. In the smart transportation IoT system, the object platform is one of the first level object sub-platforms of the smart city object platform, mainly for various city-wide information such as people flow information, car flow information, parking lot usage information, etc. Detects traffic information and performs smart control of traffic. Support by physical entities is required to realize the function. In the case of the smart traffic object sub-platform, its detection function is mainly realized by various detection devices installed in streets and alleys. For example, cameras, earth coils, geomagnetic sensors, microwave detectors, GPS locators, RFID devices, etc. Its control function is mainly to realize traffic guidance by signal lights, electronic displays, and the like. Similarly, in the case of the smart medical object sub-platform, it is to realize the detection and corresponding control of medical related information such as patient information, bed information and doctor information. In the case of the smart energy object sub-platform, it is to detect energy usage information such as water, electricity, gas, heat, energy security information, equipment failure information, etc. and execute corresponding control.

Smart city object platforms are multi-level, with first-level object sub-platforms by industry or sector, as well as first-level object sub-platforms in the same industry or sector, depending on a particular product or corresponding characteristic. It is further divided to form a second level object subplatform, and the second level object subplatform is further divided into a third level object subplatform. In this way, it is subdivided into the object platform of the lowest level IoT unit. In the following, the subdivision of the object sub-platforms of smart transportation, smart medical care, and smart energy will be taken as an example.

In the field of smart transportation, the smart transportation of the whole city consists of the gradual integration of the smart transportation of each ward / prefecture and the smart transportation of each street. Therefore, in the city-wide smart traffic composite IoT system, the object platform integrates the city-wide traffic information detection function and the traffic control execution function as the first-level object sub-platform of the object platform of the smart city composite IoT system. be able to. This first-level smart traffic object sub-platform is formed by the urban traffic structure by integrating the object platform of the smart traffic complex IoT system of each ward / prefecture of the whole city. Therefore, the smart transportation object platform of each of these wards / prefectures can be regarded as a second-level object sub-platform. They detect traffic information of the corresponding ward / prefecture and execute traffic control. Similarly, for these smart traffic object sub-platforms of each ward / prefecture, the object platform functions of the smart traffic composite IoT system of each street in each ward / prefecture will be integrated, so that the smart traffic composite IoT system of each street in each ward / prefecture will be integrated. The object platform can be a third level object subplatform. They detect traffic information on the corresponding streets and perform traffic control. Due to the richness of smart transportation functions, the smart transportation complex IoT system on the same street has many different types of IoT units with different smart transportation service functions. Therefore, the smart traffic object sub-platform of each street of the third level is composed of the object platforms of these many IoT units. That is, the object platform of these IoT units is the smallest component of the smart city object platform in the field of smart transportation.

In the field of smart medical care, the smart medical care complex IoT system for the entire city is composed of the smart medical care complex IoT system of each ward / prefecture. The smart medical complex IoT system of each ward / prefecture is composed of the smart medical complex IoT system of each hospital. The smart medical complex IoT system of the same hospital is composed of various types of IoT units that realize various smart medical service functions. Therefore, first, the object platform of the smart medical complex IoT system of the entire city can be used as the first-level object platform of the object platform of the smart stay composite IoT system. It integrates the functions of medical information detection and medical control execution of the smart medical complex IoT system for the entire city. Since the first-level smart medical object sub-platform of the entire city is composed of the object platform of the smart medical complex IoT system of each ward / prefecture of the city, the object platform of the smart medical complex IoT system in each ward / prefecture of the city is It can be considered as a second level object subplatform. These mainly realize the function of detecting medical information of the corresponding ward / prefecture and the function of executing medical control. Similarly, the second level smart medical object subplatform of each ward / prefecture is composed of the object platform of the smart medical complex IoT system of each hospital in the corresponding ward / prefecture, so that the smart medical complex IoT of each hospital The system's object platform can be considered as a third level object subplatform. These mainly realize the function of detecting medical information of the corresponding hospital and the function of executing medical control. Due to the variety of smart medical service functions, the smart medical combined IoT system of the same hospital is also equipped with a large number of IoT units for realizing various smart medical service functions. The object platform of these IoT units constitutes the object platform of the hospital-level smart medical complex IoT system. That is, the object platform of these IoT units is the smallest component of the smart city object platform in the field of smart medicine.

In the field of smart energy, it is divided into four types, water, electricity, gas, and heat, depending on the type of energy, and it is divided into public energy and household energy according to the nature of energy use. Therefore, the city-wide smart energy object platform, as the first-level object sub-platform of the smart city object platform, integrates the energy information detection function and the energy control execution function in the entire city. This first level smart energy object subplatform consists of various energy types of composite IoT system object platforms, smart water business object subplatform, smart power object subplatform, smart gas object subplatform, smart thermal energy object. Includes sub-platforms. These object sub-platforms can realize the detection and control function of the composite IoT system in each corresponding energy field as the second level object sub-platform in the energy field of the smart city. Similarly, second-level object sub-platforms of different energy types are further subdivided into third-level object sub-platforms of different usage properties. For example, the smart water business object sub-platform can be divided into a smart public water business object sub-platform and a smart household water business object sub-platform. The smart power object sub-platform is divided into a smart public power object sub-platform and a smart household power object sub-platform. The smart gas object sub-platform is divided into a smart public gas object sub-platform and a smart household gas object sub-platform. The smart thermal energy object subplatform is divided into a smart public thermal energy object subplatform and a smart household thermal energy object subplatform.
